ABSTRACT:
A viewpoint detection device comprises a viewpoint detection circuit which detects a position of viewpoint of an operator, a memory for storing detection information from the viewpoint detection circuit in a case where the position of the viewpoint is properly detected, and a correction circuit which compensates an output of the viewpoint detection circuit by using detection information stored in the memory, when the detection of the position of viewpoint is not conducted properly by the viewpoint detection circuit.
